Magic 105.4 has knocked Global Radio's Capital from the number one spot in the hotly contested London commercial market with a record audience of nearly 2.3 million listeners.

The Bauer Media station grew its listenership by 14% on the previous quarter to 2.29 million, with a market-leading 6.1% share of the audience in the second quarter of this year, according to official Rajar figures published on Thursday.

It slipped to second place in terms of reach, down 4.7% on the previous quarter to 2.08 million, and third place in terms of market share with 4.8%, behind sister station Heart, which had 5.1%.

Heart took third spot in terms of reach, down 5.6% on the previous quarter to 1.99 million.

Bauer's Kiss stayed in fourth place in the capital, with 1.86 million listeners and a 4.3% share of the market.

Capital's Johnny Vaughan and Lisa Snowdon held on to the commercial breakfast show crown in the capital, with 1.14 million listeners, ahead of Magic's Neil Fox, with 845,000.

Heart breakfast duo Jamie Theakston and Harriet Scott, with an audience of 792,000, were just a whisker ahead of Kiss's Rickie, Melvin and Charlie, with 789,000.

Vanessa Feltz, who debuted with a record audience on the BBC Radio 2 early breakfast show, also had her biggest ever audience for her BBC London 94.9 morning show, up more than 100% year on year to 275,000.

It helped BBC London – which also saw a record audience for the returning Danny Baker – to an average weekly reach of 554,000, down marginally on the previous quarter but up 9% year on year.

Global's talk station LBC was down 8% on the previous quarter to 861,000. It had a 3.4% share of the market.
